Answer:
The angle through which the wheel turned is 947.7 rad.
Explanation:
initial angular velocity, = 33.3 rad/s
angular acceleration, α = 2.15 rad/s²
final angular velocity, = 72 rad/s
angle the wheel turned, θ = ?
The angle through which the wheel turned can be calculated by applying the following kinematic equation;
Therefore, the angle through which the wheel turned is 947.7 rad.
Answer:
Explanation:
Case I: They have same charge.
Charge on each sphere = q
Distance between them, d = 14.8 cm = 0.148 m
Repulsive force, F = 0.235 N
Use Coulomb's law in electrostatics
By substituting the values
Thus, the charge on each sphere is .
Case II:
Charge on first sphere = 4q
Charge on second sphere = q
distance between them, d = 0.148 m
Force between them, F = 0.235 N
Use Coulomb's law in electrostatics
By substituting the values
Thus, the charge on second sphere is and the charge on first sphere is
.
